Mods can promote/demote with their moderator magic powers, so some members will not follow the path or will get stuck with the same icon forever as a form of punishment or asking for promotion or change in icon. But the rest of the Team Liquid population follows what is written above, so behave and one day you too can be a beautiful Ultralisk.
